Seedling management: the temperature and humidity environment in spring is more suitable for the growth of African violets, pay attention not to pour water directly on the leaf surface and make the leaves rot, watering should gently hold up the leaves with a pointed pot directly poured on the pot soil, when the air humidity is small, you can spray water on the foliage, African violets avoid thick fertilizer, thin fertilizer more methods, spray new high fat film fertilizer and moisture.

Flowering management: Less fertilization should be applied during the flowering period, fertilization will shorten the flowering time. Spraying the flowers can promote strong buds, hypertrophic petals, bright flower color, rich floral fragrance and prolonged flowering period.

Winter management: In winter, due to the weak sunlight, fluorescent lamps should be used to supplement the irradiation to make up for the lack of sunlight, move to the balcony at noon to get sunlight, reduce watering and fertilization, and the water watered in winter should be properly heated. Keeping the room temperature at around 20 in an air-conditioned home will allow it to grow and bloom properly.
